Fields

explain_metrics: Option<ExplainMetrics>

Query explain metrics. This is only present when the RunAggregationQueryRequest.explain_options is provided, and it is sent only once with the last response in the stream.

read_time: Option<DateTime<Utc>>

The time at which the aggregate result was computed. This is always monotonically increasing; in this case, the previous AggregationResult in the result stream are guaranteed not to have changed between their read_time and this one. If the query returns no results, a response with read_time and no result will be sent, and this represents the time at which the query was run.

result: Option<AggregationResult>

A single aggregation result. Not present when reporting partial progress.

transaction: Option<Vec<u8>>

The transaction that was started as part of this request. Only present on the first response when the request requested to start a new transaction.
